Abstract: A shoe patch device and method of preserving and repairing shoes is disclosed wherein a patch member fabricated of a thin, flexible and durable material is formed to be rapidly adhered to the sole and/or upper of the shoe. The patch member is formed in a suitable configuration and includes a plurality of V-shaped notches extending inwardly from its edges to permit the patch member to readily accommodate all shoe sizes and be positioned at differing locations upon the shoe. Due to the lightweight and flexible properties of the patch member, the function and wear characteristics of the shoe are not altered or impaired, nor is it necessary to disturb the original construction of the shoe to effectuate repair or preservation of the shoe.

Abstract: This invention provides a convenient apparatus and method for mounting equipment in an underground vault to provide convenient access to the equipment whenever such access is necessary. The vault mount includes a frame having one end thereof permanently pivotally mounted to the frame releasably attached to a second wall of the vault. Suitable springs are mounted between the first wall of the vault and the frame to urge the frame to pivot about the mounting to the first wall. When the second end of the frame is released from its wall mount, the frame and the apparatus mounted thereon pivots from a generally horizontal position in the vault to a generally vertical position with the equipment mounted on the frame extending out of the vault.

Abstract: This invention relates to an improved air driven pump for pumping products such as beverage syrups. Two opposed pistons are mounted on a common piston shaft for reciprocal movement within a housing. Cavities corresponding to the pistons are alternately vented and pressurized to intake the product into a pair of cylinders and to drive the pistons to pump the product. A spool valve stem extends into the cavity being vented so that the piston performing an intake stroke moves the valve stem into the other cavity. A pair of axial passages and corresponding side openings in the valve stem provide fluid flow paths for venting and pressurizing the cavities. A valve body biased toward the cavity being vented includes a vent passage for alternately venting the cavities through the side inlets. While one cavity vents, pressurized fluid flows into the other cavity through the corresponding side inlet and axial passage.

Abstract: A truss boom having an extension member equipped with a pulley and a hook, comprising a pyramidal support frame is disclosed.

Abstract: An improved microwave field monitor device is disclosed characterized by use of a microstrip antenna and control electronics adapted to provide a field alarm, field monitor, accumulated dose alarm, and integrated dose indication of RF radiation exposure to an individual. The monitor is packaged in a small configuration similar to an identification badge adapted to be easily affixed to the clothing of a user. The monitor additionally is capable of measuring the RF radiation exposure at particular part or whole body resonance frequency bands or standing wave hot spots known to be hazardous to individuals.

Abstract: A self-tapping, self-drilling orthopedic fixation screw includes a cannula through the shaft of the screw for placement over a guide pin mounted in a guide hole in a bone to drill and tap a hole at predetermined location in the bone.

Abstract: An intramedullar rod is formed as a hollow cylinder with slits therein that form a plurality of leaf spring members that bend inward when the rod is inserted into the medullary cavity of the bone.

Abstract: A variable resistance exercise apparatus is disclosed specifically adapted to provide an improved method or aerobic and anaerobic exercising of the upper extremities and upper body portion of a user. The apparatus is characterized by the use of a hand crank assembly adjustably positioned at a vertical height above a support platform to cause a user to reach and twist during exercise upon the apparatus. The length of the hand crank assembly may be adjusted to accommodate differing extremity lengths of the particular user and the exercise resistance load applied to the hand crank may be varied to accommodate both professional athletic training as well as residential fitness programs.

Abstract: A polypeptide having the cell-attaching activity of fibronectin. The polypeptide has 108 amino acid residues and the formula: H-Ile-Gly-Gln-Gln-Ser-Thr-Val-Ser-Asp-Val-Pro-Arg-Asp-Leu-Glu-Val-Val-Ala- Ala-Thr-Pro-Thr-Ser-Leu-Leu-Ile-Ser-Trp-Asp-Ala-Pro-Ala-Val-Thr-Val-Arg-Tyr -Tyr-Arg-Ile-Thr-Tyr-Gly-Glu-Thr-Gly-Gly-Asn-Ser-Pro-Val-Gln-Glu-Phe-Thr-Va l-Pro-Gly-Ser-Lys-Ser-Thr- la-Thr-Ile-Ser-Gly-Leu-Lys-Pro-Gly-Val-Asp-Tyr-Thr-Ile-Thr-Val-Tyr-Ala-Val -Thr-Gly-Arg-Gly-Asp-Ser-Pro-Ala-Ser-Ser-Lys-Pro-Ile-Ser-Ile-Asn-Tyr-Arg-Th r-Glu-Ile-Asp-Lys-Pro-Ser-Gln-Met-OH. The polypeptide or a biologically active fragment thereof can be employed in the preparation of substrata designed for the attachment of cells thereto. It can be linked to the surface of a prosthetic device to particularly attract endothelial cells and fibroblastic cells.

Abstract: A high precision, high pressure, volumetric metering pump in which the driving motor is reciprocated by rotation of a ball screw, the drive motor assembly being integral with the driving and pumping shaft, is disclosed.

Abstract: An improved apparatus and method for hydraulically mining unconsolidated subterranean mineral formations is disclosed wherein the hydraulic mining tool and surface drilling equipment is supported upon elongate structural beams releasably affixed at opposite ends to laterally spaced concrete foundations positioned upon the drilling site. The structural beams prevent the mining tool from canting or subsiding during the hydraulic mining process and may be reused for consecutive mining operations at differing locations upon the drilling site. An improved mining tool configuration is additionally disclosed which is specifically adapted to agitate and maintain the mined minerals in suspension within the mining slurry and further direct the slurry toward the mining tool for subsequent transport to ground surface.

Abstract: A vibrationless percussion tool is disclosed characterized by use of a piston mounted for reciprocal movement against a constant pressure force within a casing to cyclically impact an anvil disposed adjacent the distal end of the casing. A spool valve is disposed within the interior of the piston and is adapted to travel in unison with the reciprocating piston except during mechanical actuation initiated adjacent the extreme downstroke and upstroke position of the piston within the casing. The constant pressure force is continuously applied to one side of the piston and by mechanical actuation of the spool valve, the volume disposed on the opposite side of the piston is alternatively vented and pressurized to cause reciprocation of the piston against the constant pressure source.

Abstract: Optical contact lenses and silicone hydride polymers therefor are disclosed.

Abstract: A ski boot having a curved bottom which includes four portions defining, during walking, a unique path for the force vector of the user's weight as the user walks and having defined angular and special relationships which make walking in a ski boot easier, safer and move convenient is described.
